What is the question to which fusion and geothermal is the answer? From a climate perspective those will come too late to aid our planet much until decades of further change, if fusion even comes at all.

Seems to me like wind solar batteries and nuclear are the answer, what’s actually being built now in a big way, not pie in the sky like fusion.

Fusion is the answer to "how can we extract R&D money for decades without ever actually delivering anything." There is little prospect it's going to be competitive, particularly DT fusion. The engineering/economic obstacles are profound even if all the plasma physics problems are solved. Most of the efforts being touted are obvious nonstarters.
